What does an internal medicine doctor do?

The doctor of Critical Medicine is a professional specialist trained in the care and treatment of seriously ill patients, or those who have suffered great trauma. Critical Medicine doctors are dedicated to the provision of life support, or support of the organic systems, in patients who are critically ill. They provide intensive supervision and monitoring as required.

This test identifies how to reduce the respiratory difficulty produced by the accumulation of fluid or air in the pleural space. It can be:


We extract several milliliters of pleural fluid to perform analysis.


We extract several hundred milliliters of pleural fluid in order to relieve patient’s symptoms.

Who needs it?

Patients with any of the following diseases:

Systemic diseases such as hypertension

Heart failure

Endometriosis or ovarian hyperstimulation

Pancreatic pseudocysts





What is the procedure?

When there is fluid in the pleura, the main goal is to drain it, prevent it from building up again, and try to find out why it has been stored.

It is a minimally invasive procedure in which a surgical puncture of the chest wall is performed to evacuate the accumulated fluid in the pleural cavity by aspiration.

What is a lumbar puncture?

Lumbar puncture is a medical procedure in which a sample of cerebrospinal fluid is removed for testing.

Cerebrospinal fluid is colorless and its function is to provide nutrients and act as protector of the brain and spinal cord, or central nervous system. This study is done to identify signs of possible infections and other important information about the patient’s health.

What is it done for?

A lumbar puncture can diagnose disorders of the central nervous system, such as: Guillain-Barré syndrome, multiple sclerosis or types of cancer in the brain or spinal cord, and serious infections such as meningitis, among others.

It is also useful for applying chemotherapy drugs to the cerebrospinal fluid or injecting anesthetic drugs.

Preoperative assessment resides in the process that precedes surgery. It is an exhaustive evaluation, in which all the patient’s information is considered including: medical history, physical examination, and para-clinical tests.

The goal of the preoperative assessment is to increase the quality of patient care and allow the patient to return to normal life as quickly as possible, as well as reducing the risks of complications, during and after surgery.

Preoperative evaluations prevent most complications as they are foreseeable and treatable.

Who needs the preoperative assessment?

Patients under 40 years of age with a known disease (diabetes mellitus, arterial hypertension, kidney, cardiovascular, hematological, liver problems, etc.)

All patients over 40 years of age, with or without diseases, undergoing elective surgery.

Surgical and / or cardiovascular high-risk patients who require immediate surgery and complex postoperative care.

What is the preoperative assessment?

The Internist is the doctor in charge of carrying out this assessment in a comprehensive manner. The cardiologist can assess cardiovascular risk.

Once all the tests have been carried out and the interviews concluded, the doctor explains the results of the evaluation in a comprehensive way, makes suggestions and adjustments to the treatment if required, and sends the report to the patient’s surgeon.

Intensive therapy is a special area of care, specifically-oriented to the medical care of patients in acute critical condition. This implies maximum support of the vital systems and functions of the body in the event of serious illness or injury.

There are several conditions for which a person can enter Intensive Care, some of the most common are:

Secondary and inherent complications of high-risk surgery. Patients who have suffered a serious accident generalized or specific infections in vital organs (lung, urinary tract, brain)

Respiratory diseases


Some types of metabolic, neurological and kidney diseases

Fatty liver / Nonalcoholic Fatty Liver

This is the generic term for multiple and varied liver conditions that affect more than 42 million people in Mexico alone.

The disease is characterized by the accumulation of fatty acids and triglycerides in liver cells, visceral fat is located inside the abdominal cavity, filtering until it reaches the liver, thus altering its functioning, preventing it from complying with all its chemical and biochemical reactions, with a progression to liver cirrhosis (Non-alcoholic) causing fibrosis and inflammation, and sometimes irreversible damage to the liver.
